SSID for VPN SSID for no vpn

[jobongo]

I am trying to setup my RT-N66U to allow one SSID to be routed over a VPN that I use and another SSID to be routed over regular internet. Can I do this with this firmware. I am comfortable with linux commands but I can't seem to find a way to do this. I would prefer not to use DD-WRT (great firmware btw) as the WAN-LAN throughput is not so great (~ 80mb/s) on this router. I have tried using ebtables to tag the frames and then route based on marked frames. I have tried to set the extra VPN SSID in a separate bridge so that IP rules can be created to route where I want but I couldn't get wireless security to work. If anyone has any ideas, I would greatly appreciate it. Thanks.
